Cowhenge.

For some reason best known to my addled brain, I'd got the wrong set of MM challenges, so I'm too late to do double exposure. Luckily I've unearthed this prehistoric monument, as equally impressive as its well known contemporary, Stonehenge.
Thanks to Carolina for hosting mono Monday and, at the risk of ingratiating myself, the extra is to all the Challenge hosts; you do a grand job.
